Title: Improvements in apparatus for soldering chain links and the like
IPC: B23K3/06
Filed: 1925-07-28
Abstract: 244,045. Wenz, J., Alvera, J., and Brunh³bner, G. Dec. 2, 1924, [Convention date]. Chains.-In soldering the links of chains &c. solder in the form of a paste or thick liquid is extruded from a receptacle on to the joints prior to closing thereof, through a passage in one or more of the link-shaping tools. Wire may be fed by the part 12 against an end abutment 14, severed bv a cutter 11 and bent bv a mandrel 13 and pincers 10 and finally closed by a tool 1 forced down by a lever z and returned by a spring 4. The tool 1 contains a solder paste 6 on which rests a loose plunger 3 and has a small aperture 8. The solder is extruded through the aperture by the momentum of the plunger 3 during the upward stroke of the tool. In Fig. 3, the end abutment 21 serves also as a solder container and has a funnel shaped opening. Solder is forced out by a spring-pressed plunger 23 and the end of the wire thus provided with solder. The wire is severed by a cutter 15 bent on the mandrel 19 by the pincers 17 and finally closed by the tool 18. The part 21 may be closed by a screw cap 25 for charging purposes. The solder may, if desired, be discharged through an opening in the upper surface of the mandrel 19, or in the side of the cutter. In Fig. 5, in which two sets of feeders, pincers, cutters, and mandrels are arranged at right angles to one another to form alternate links as described in Specification 251,699, [Class 83 (iv), Metals, Working], the mandrels 36, 44, which are pressed forward by springs 40, 48 and returned by rods attached to the feeders 27, 41 engaging rods f carried by the mandrels, are used as containers for solder which is ejected by spring-pressed plungers 33, 46. The mandrels are provided with side cover plates for charging purposes. The links are finally closed by a tool with a cruciform groove. In any of the forms the plungers may be operated positively by worm gear. The solder may be carried by separate receptacles communicating by a passage with the link-forming tools. When the solder is supplied to movable tools, these may serve to cut off the supply of solder amd thus relieve the pressure thereon.

Title: Sensitivity control device

Abstract: 1,204,296. Laser radar. BOFORS A.B. 17 April, 1969 [17 April, 1968], No. 19747/69. Heading H4D. [Also in Division G1] In a light pulse, e.g. laser, ranging receiver, wherein noise rejection is provided by imposing a fixed threshold below which pulses are not passed from the detector to the utilizing means, the maximum operating range of the receiver is limited to that at which the target echoes are greater than said threshold. To overcome this drawback the invention proposes varying the relation between the threshold and amplitude of the pulses produced by the detector in dependence on the number of pulses occurring above the present threshold, whereby for example in the case of a " quiet " background the threshold may be lowered and the maximum range of the receiver increased. In the illustrated embodiment the output of the photomultiplier 1 is fed to a variable threshold amplifier 2 the output of which feeds utilization means at 3 and also a pulse repetition frequency counter 4. The output of 4 is a voltage proportional to the number of pulses (noise plus echoes) above the threshold, and is compared in comparator 5 with a reference voltage from 6. The output of 5, representing the difference between the two input voltages, is used at 7 to vary the threshold of the amplifier 2. Alternatively, as shown by connection 8, said output can be used to control the voltages feeding the various electrodes of the photomultiplier 1 whereby the amplitudes of the pulses from the detection are varied.

Title: Braun tube, more particularly for television purposes
IPC: H01J29/74
Filed: 1933-07-13
Abstract: 427,090. Cathode-ray tubes. HUDEC, E., 17, Potsdamerstrasse, S³dende, Berlin. July 13, 1933, No. 19781. Convention date, July 13, 1932. [Class 39 (i)] In Braun tubes operating with a single ray of electrons, one pair of plates for deflecting the ray to scan the screen is so formed that the deflecting field is much stronger at all points near one plate than near the other. The plates P1, P<1>1, Fig. 2, may be cylindrically curved to give the non-uniform field shown. The plate P1 is connected to the anode A and the undeflected ray is nearer the negative plate P<1>1. As the deflection increases, the deflecting field decreases to compensate for the decrease in the speed of the electrons and so to keep the deflection proportional to the deflecting voltage. In modifications, flat plates of different length or width are used or one plate may be divided to form a main part d, Fig. 4, and small parts b, b<1> at one or each end or side of the part d, the parts b, b<1> being connected to the opposite plate P or to a fixed potential. The part b may shield the other pair of deflecting plates from the variable field of the plate d to avoid trapezoidal distortion of the image. Instead of maintaining the ratio of deflection to deflecting voltage constant, the usual increase in the ratio with increasing voltage may be exaggerated, for example, if the potential does not increase linearly with time. Specification 380,381 is referred to.
